NAME
       elf_getident - retrieve file identification data

SYNOPSIS
       [flag... ] file...  [library] ...

DESCRIPTION
       As  elf(3E)  explains,  ELF provides a framework for various classes of files, where basic objects may have 32 bits, 64 bits, and so forth.
       To accommodate these differences, without forcing the larger sizes on smaller machines, the initial bytes in an ELF file  hold  identifica-
       tion information common to all file classes.  Every ELF header's has bytes with the following interpretation.

						 e_ident Index	 Value		  Purpose
						 --------------------------------------------------------
						 EI_MAG0	 ELFMAG0	  File identification
						 EI_MAG1	 ELFMAG1
						 EI_MAG2	 ELFMAG2
						 EI_MAG3	 ELFMAG3
						 --------------------------------------------------------
						 EI_CLASS	 ELFCLASSNONE	  File class
								 ELFCLASS32
								 ELFCLASS64
						 --------------------------------------------------------
						 EI_DATA	 ELFDATANONE	  Data encoding
								 ELFDATA2LSB
								 ELFDATA2MSB
						 --------------------------------------------------------
						 EI_VERSION	 EV_CURRENT	  File version
						 --------------------------------------------------------
						 EI_OSABI	 ELFOSABI_NONE	  OS/ABI identification
								 ELFOSABI_HPUX
						 --------------------------------------------------------
						 EI_ABIVERSION	 0		  ABI version
								 1
						 --------------------------------------------------------
						 EI_PAD 			  Start of padding bytes

						 --------------------------------------------------------
						 10-15		 0		  Unused, set to zero
						 --------------------------------------------------------

       Other kinds of files (see elf_kind(3E)) also may have identification data, though they would not conform to

       returns	a  pointer  to	the  file's ``initial bytes.''	If the library recognizes the file, a conversion from the file image to the memory
       image may occur.  In any case, the identification bytes are guaranteed not to have been modified, though the size of  the  unmodified  area
       depends	on  the file type.  If ptr is non-null, the library stores the number of identification bytes in the location to which ptr points.
       If no data is present, elf is null, or an error occurs, the return value is a null pointer, with zero optionally stored through ptr.
